NXP Semiconductors

LPC2361/62

Single-chip 16-bit/32-bit MCU

14.5 Standard I/O pin configuration

Figure 25 shows the possible pin modes for standard I/O pins with analog input function:

• Digital output driver

• Digital input: Pull-up enabled/disabled

• Digital input: Pull-down enabled/disabled

• Analog input (for ADC input channels)

The default configuration for standard I/O pins is input with pull-up enabled. The weak

MOS devices provide a drive capability equivalent to pull-up and pull-down resistors.
